Improvement in skates



UNITED STATES PATENT OEETCE.

CHARLES H. MARVIN, OF NEW YORK, N. Y.

IMPROVEMNT IN SKATES.

Specification forming part of Letters Patent No. 38,173, dated April 14, 1863.

To @ZZ whom it may concern:-

Beit known that I, CHARLES H. MARVIN, ot' the city, county, and State of New York, have 'invented a new and useful Improvement in Skates; and I do hereby declare that thel following is afull, clear, and eXact description ot' the same, reference being had to the ac companying drawings, making a part of this spccication, in which- Figure l is a side view ot' a skate, partly in section, as indicated b y the line .r af, Fig. 2, and having my improvement applied to it; Fig. 2, a bottom view or inverted plan of the same; Fig. 3, a bottom view of a nut which is secured to the heel of the boot or shoe to which my invention is designed to be applied; Fig. 4, a detached longitudinal section of the nut, taken in the line y y, Fig. 3; Fig. 5, a detached view of a screw plug designed for the nut. when the latter is not in use.

Similar letters of reference indicate correspending parts in the several ligures.

This invention relates to an improved mode ot attaching the back part ot? the skate to the heel of the boot or shoe, whereby a very firm attachment ot" the aforesaid part is obtained, and by a means which will admit of the parts being attached and detached with the greatA est facility.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the stock or footstand of a skate, and B the runner thereof'. These parts may be constructed in the usual way, and therefore do not require a minute description.

The front part ofthe skate'is attached to the foot by means of straps C C, firmly secured at their lower ends to the sides of the stock A, the upper ends ot' the straps being provided with eyeletholes, through which a string, D, passes. Any other suitable fastening, however, may be employed for securing the front part ofthe skate to the foot.

In the back part ot' the stock A there is fitted vertically a screw, E. This screw is provided at its lower end with a head, a., which is fitted in a recess, B, in the upper part of the runner. The screw is allowed to turn freely in the stock A, and the head a is slotted radially to admit ot' a small wrench or lever being applied to it to turn the screw.

A washer, c, is interposed between the head c and the stock. The screw E projects above the upper surface of the stock A, as shown in Fig. l.

F is a nut, the internal thread, d, ot' which receives the thread of screw E when the back part of the skate is secured to the heel ofthe boot or shoe. This nut F is provided with two arms, e e, which project from its opposite points, and these arms have holes f made in them to allow screws g to pass through and into the heel ot' the boot or shoe. The nut F is let into the heel of the boot or shoe, so that its lower surface will be ush with the under surface of the heel, the screws g firmly securing the nut to the heel.

From the above description it will be seen that in order to attach the back part of the skate to the heel of the boot the former is adjusted to the sole and heel of the latter, and the upper end of the screw E is screwed into the nut F. The screw E is turned first by the thumb and finger, and then by inserting a wrench or barin the slots in the head a of the screw. By this means the back part of the stock A is firmly secured to the heel.

G is a strap which passes through the back partot' the stock A and is buckled over the instep. This strap is necessary in case a loose boot or shoe is worn, as it prevents the working ofthe foot in the latter.

When the skate is not applied to the boot or shoe, the hole in the nut F is filled by a screw-plug, H, (shown in Fig. 5,) which prevents said nut being filled with dirt.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

Having th\j heel part ot' the skate provided with a rotating screw, the point and thread of which project above the surface of the skate foot-piece and enter a nut in the boot-heel, while the head of said screw is placed below the foot-piece and projects beyond the sides of the runner, as herein shown and described, so that by turning the head ot' said screw the skate may be quickly fastened to or removed from the foot, all as set foi th.
